Master Lock No. M1BQAU Excell Padlock
The Master Lock No. M1BQAU is engineered with the toughest boron alloy materials and advanced patented technology—boasting over 40 registered patents—to deliver Excell, a padlock that is up to 50% stronger than standard locks.
Built with a laminated steel body and a weather-resistant brass cover, this lock is designed to withstand even the harshest outdoor conditions. Its tough-cut boron carbide shackle is 50% harder than hardened steel, while the patented octagonal shape makes it far more difficult for bolt cutters to grip.
For added versatility, the lock offers increased shackle clearance to suit a wide range of applications. A professional-grade ball bearing locking mechanism ensures maximum resistance against pulling and prying, delivering reliable high-security protection.
